I knew football would be number one, but with a large influx of successful NBA players from the region (but not Czechia) in particular, I was wondering if there has been any growth in the sport, given that it requires less money than hockey, but still more pricey than football.

Well there are literal differences in rules, albeit typically minor, and the ball is slightly smaller but the style of play is different. Euroball looks like NCAA play with better shooting, whereas the NBA has more hero ball and above the rim play.
